ln said drawing, 2() des'` ares the corner post of thesiipeifi-structure `of a `closed type of automobile to which nivimproved spot l t ai adapted te he ate had. .it portion ofthe side doorof the automobile is indicated at 21.. Although my improved spot lightmay be applied to wind shields of open ears, in this instance it isillustrated as applied to a closed car, the same being primarilydesigned for the latter use and readily accessible for operation fromthe interior of the car at a point convenient to the driver and inproximity to the usual steering wheel.

In carrying out my invention, I employ a pair oit suitable brackets22-22 which are secured to the outer side of the corner post 2() byscrews or any other suitable fastening devices. Each bracket 2Q isprovided with an outstanding, horizontally disposed arm 23 extending atright angles from one end of the baseportion thereof. At the outer endof the arm, extending at `right angles thereto and termed integraltherewith, is a vertically disposed trunnion 24. The brackets 22 arereversely arranged, being disposed in spaced relation with the trunnionsQ4 thereof in alinement and extending toward each other. Supported bythe brackets 22 is a tubular bearing sleeve Q as ole-arly showniniFigures l and 2, the bearing sleeve being enlarged at the inner endas indicated at 2G, providing a head of rectangular cross-section havinga vertically disposed openingr adapted to receive the trunnions 24. ItWill be evident that the sleeve 25 is thus pivotally mount-ed formovementhorizontally so that the sa me may be adjusted to any desiredangle with reference to the brackets 22 and the corner post 20.

To provide sutlicient clearance to permit the horizontal pivotalmovement ofthe sleeve, the inner end of the head is preferably cut awayon a curve concentric with thev opening 27 as clearly shown in Figure 1.The head QG isenelosed by a relatively short sleeve 28 corresponding insection to the rectangular' crosssection of the forme-r and snuglyfitting the same. The inner end of the sleeve abuts the outer surface ofthe post 20 and is cut away at an angle to properly tit the same. lVhenthe parts are assembled, the sleeve Q8 is held in fixed position by thetrunnions 2l `which extend through alined openings 29 at the top andbottom of the sleeve registering with the opening 27.

Rotatably mounted with respect 'to the bearing slee ve Q5 and thesupport formed by thebraelcets Q2 is what may be termed gein orally, aiiorisag A carrying a lamp head or shell l5, bodily rotatable therewithand also at right angles thereto. Said housing- A, as shown, preferablyconsists of a casting having a main, vertically extending, generallycylindrical section 3() 'from which is extended laterally a. cylindricaltubular sleeve 3l, the latter being disposed (zo-axially with relereneeto the bearing sleeve 9,5 and ournaled thereon. Extending into andrigidly secured to the sleeve 3l, as by a screw 32, or any othersuit-ahh` means, is a hollow operating arm 33, a spacing sleeve Silthrough which the set screw 32 extends, being interposed between the armand the interior surface ot the sleeve 3l. As clearly shown in Figure l,the eollar is spaced Ytrom the outer free end of the bearing sleeve :25,a relatively thick collar 35 oit insiiilating material being interposed,the latter being normally slightly spaced from the tree end ot thebeariiig sleeve, as clearly shown in the drawing, and lined to thecollar 3% by a hey 340 lior rotation in unison therewith.

The operating arm 83 is housed within a snugly fitting` tubular casing3o, the front portion of which telescoped Within the bearing sleeve 25protruding beyond the lfront end of the latter and eixteiulingL throughthe collar 35 and terminating l'lush with the outer side of the latter.The casing 3G passes through the post 2O and is supported by a bracket37 secured to the inner side of the post.

The bra clet 37 comprises a hollow hub-like portion 38 through which theeasing 3G extends, and a pair ollv oppositely extending, verticallydisposed supporting ari'ns 3l) -t'oruied integral with the liront end olthe hub and having their tree ends secured to the post by means ofscrews or any other suitable taetenin devices. The bracket 37 ispreferably torn'ied ol" bendable metal so that the arms 3l) may bereadily bent or twisted witliout any danger ot breakage, to properly titthe bracket to the post E/ll). The casing lo is tight v clamped to thebracket 37 by an eX ternally threaded, split conical sleeve 40, disposedwithin theopening ot the hub and surrouinling the easing, the opening inthe hub being rearwardly tapered, as shown, to torce the sleeve tocontract when moved rearwardly relatively to the hub. The sleeve l0 isappreciably longer than the hub and has the threaded portion thereotprotruding rearwardly ot the hub. An internally threaded, l-tnurledcollar Lil, adapted to abiiit the rear end of the hub 3S, is screwedonto the sleeve lll, draiviiig the same inwardly, rearwardly ol1 the hubto Contract the sleeve to tightly clamp the casing to the braeltet 37.The sleeve 4l) is preferably splined on the easing 3o by means of' a key42, thereby permitting loiigitudinal movement thereof relatively to theeasing While preventing relative rotation. The supporting means formedby the braeliet 37 provides tor adjustment ol the casing at variousangles with respect lo the post 2() due to the bendable nature ot thearms 3l).

To operate the spot light with the utmost. convenience, l provide meansmanipulated by one hand ot the operator to e'l'lfect both the operationol the mechanism tor producing bodily :Swinging movement ot the lampluad with the oirierating arm B2i, and the nicchanisin lor producingindcpeiuleut rotation ot the lamp head at right angles thereto. Themechanism for rotating the arni ll includes a casting ell in the lorm ola` housing rigidly secured to the operating arm lil and provided with alaterally extendii'ig, cylindrical sleeve LlLl formed integraltherewith, the lutter being disposed near the rear end. ot' the housing.ilu operating hand grip l5 is secured to the housing, the salue lniingprovided with au. axial bore elli, adapted to receive the cylin-1 drilal sleeve lll, the hand grip boing rotatably mounted on the sleeve `lora purpose hereinalfter described.

rl`he housing Li3 is provided with a bore (il), coaxial with the casing8G, adapted lo receive lthe rear end portion ot the operatingl arm ll.its clearly shown in Figure l, the rear end oll the casing SHS normallyabuts the housing` lil and the arm 333 protrinles beyond the cud ot thecasini'. At the iront end.` the housing is split as indicated at el?. Aclamping screw extending through the split portion` oilI the housing andengraving a shallow reco-fs el@ in the arm 38 servi to draw the splitportion together and tightly clamp the housing lo the arm, the screwcoacting with the reeessed portion to assist in preventing relativerotation ot the parts. It will be evident that, upon swinging the handgrip in either a right or leltdiand direction, the arm 2li-l Will berotated thcrewi lh, ellecliiuij a corrosimnd ing swingi ng movement olIthe lamp head l); with the using A, which is rigidly secured to the armll as hercinbe'liore described.

rlhe mechanism for effecting rotation of the lamp head at right anglesto the axis o1l" rotation ol the housing A is also operated through themanipulatitm of the hand grip 45, by rotating the latter about thelongitudinal axis o the sleeve 4 4'. The mechanism tor rotating the lamphead B at right angles to the direetion of rotation oil the housing Aincludes a. beveled gear 49 ln'ovided with a. stem 5() rotatablymounted. in the bore of the sleeve 44:, the lower end of the stem beingrigidly secured to the hand grip in any suitable manner so that the gearis positively rotated thereby. The stein 5() is prete ably secured tothe hand grip by a driving lit within a reduced porti ou 5l of the bore4:6. To rotatably retain the gear 49 and the hand grip l5 in assen'ibledrelation with the housing 43, a set screw 52 extending through the lowerend of the housing and its inner end engaged in an annular groove 53near the upper end of the stem 50.

lill) lll) rlhe beveled gear 49 meshes with a second beveled gear 54formed integral witha spur gear 55 having a hub portion 56 journaled ina bearing opening 57 formed in the housing immediately below the bore60. A coiled spring 58 is interposed between the inner end of the hub 56and the bottom of the opening 57 to force the beveled gear 54 into closeengagement with the gear 49 to prevent looseness and avoid rattling ofthe parts. The spur gea-r 55 meshes with a second spur gear 59 providedwith a hollow hub 61 rotatably mounted in an enlarged portion 62 of thebore of the housing. The openingr of the hub 6l is preferably ofrectangular cross-section and the gear 59 is rigidly secured to arelatively long, hollow operating shaft 63, having the rear end thereofof square cross-section and received within the square opening of thegear 5S).

The operating shaft 63 extends axially through the arm 33 and isrotatably mounted therein, the arm 33 serving as a bearing for the same.The front end portion of the shaft 63, as clearly shown in Figure 1,extends beyond the corresponding end of the arm 33 and into thecylindrical section of the housing A, and has a worin rigidly securedthereto, meshed with a worm gear 64 rigidly secured to a hollow stubshaft 65 having its lower end rigid with a thimble like sleeve 66,tightly .lined in the upward extension 67 of the lamp head B. The outerend of the shaft 63 is journaled in a vertically disposed wall 167,preferably formed integral with the housing A and spaced inwardly fromthe front end of the latter.

The stub shaft 65 is rotatably supported in the cylindrical section 30of the housing by an adjustable bearing comprising, a bearing sleeve 68tightly fitting the interior of the section 30, a bearing cone 69 rigidwith the shaft 65 and preferably formed integral therewith, and aplurality of ball bearings 7() interposed between the sleeve and coneand carried in a ball retaining ring 7l. To resist wear, both the sleeve68 and the cone 69 are preferably formed of steel. The sleeve 68 isformed with a ball raceway having a downwardly Vtapering wall 72, thedegree of taper ot the all 72 being less than that of the cone 6i), sothat the ball bearings 7 (l will be wedged between the cone 69 and thesleeve 68 when the ring'7lA carrying the same is forced upwardly to takeup for wear. Above the 'all 72, the interior of the sleeve is preferablycut away as indicated at 73 to provide ample clearance for the ballbearings and retaining ring to permit adjustment upwardly relatively tothe sleeve 68. The mouth of the sleeve at the lower end is flaredoutwardly as indicated at 79, for a purpose hereinafter described. Thering 7l is supported by a plurality of vertically disposed, adjustablepush rods 7 3 circularly arranged about the shaft 65 and slidablymovable within vertical bores 74 in the bottom wall of the thimble 66.The lower ends of the push rods 73 protrude beyond the thimble and aresupported by a colla-r or nut 75 screwed onto the protruding lower endof the stub shaft 65. The parts are so proportioned that the upper sideof the nut is normally spaced from the lowerend of the thimble 66 topermit adjustment of the nut on the shaft 65 to lift the rods 73 andforce the ring 7l upwardly thereby adjusting the ball bearings tocompensate for wear as hereinafter pointed out. A lock nut 76 alsoscrewed onto shaft 65 serves to prevent accidental movement of the nut75. It will be evident that, when the parts are assembled, the shaft andthe lamp `head B carried thereby are supported entirely by the ballbearing arrangement just 1described, the upperA end of the thimble beingheld snugly engaged with the lower end of the section 30. The upper endof the shaft 65 is rotatably mounted in a bearing opening 77 in ahorizontal partition 7S.` theV shaft 65 being free to slide in theopening 77 so that the same may be readily entered therein when theparts are being assembled. It will be evident that the ball bearing maybe finely adjusted by the described means to prevent rattling of theparts and also provide ref sistance to rotary movement of the head B toprevent the latter from being thrown accidentally out of adjustedposition by jarring or to prevent over-rotation of the same. Inassembling the lamp head B with the housing A, the rods are firstwithdrawn from the thimble to an extent to permit the ball carrying ring7l to rest on the inner surface of the bot-tom wall ofthe thilnble 66.The lamp i head is then placed in position by passing Jche shaft 65 intothe section 30 and entering its upper end in the opening 77. The ring 7lis then pushed upwardly by adjusting the rods 73. As the ring is movedupwardly, the ball bearing 70 will be guided and forced toward the axisof the shaft 65 by engagement with the outwardly flaring wall 79 of thesleeve. The adjustn'ieut of the ring is continued until the balls arebrougl'it into engagement with the cone and forced outwardly intocontact with the wall 72.

In making the electric circuit, I preferalilly employ the so calledgrounded system. the source of electricenergy being derived from theusual storage battery found on automobiles. From the battery are led twoin sulated wires up to the spot light. The end of the negative wire ispre'l'erably soldered or otherwise secured to the metal bracket 38 asindicated at 80, being herein shown as clamped beneath the head of thescrew by which one of the arms 39 is secured. The positive wire is ledthrough a bore 8l extendinglongitudinally of the bearing sleeve 25 andto one side of the axis thereof, the end of thepostive wire beingelectrifally connected to a spring conni'iulntor or Contact ring 82mount ed in an annular groove 83 ot' a ring of insulating material 81fitted within an annular groove in the outer end ot the bearing sleeve25. A contact rino" 85 lined in an annular groove et the collar d5 etinsulating material coacts with the ring 82, being yieldingly engaged bythe projecting portion of the latter. The ring 85 is electricallyconnected to a bowed contact spring 86 by inea-ns ot a short insulatedwire 87 led through openings in the partition 78 and the collar 31. Thesprinov arm 86 terms a part ot' a switch, one end or said arin beingclamped between a ring U8 o1 insulating` material and the annular Harigeoli a sleeve like washer 89 extending through the spring` and held by ascrew 00. The end ot' the wire 87 is preferably provided with a terminallug ot well known torni, which is clamped between the flange ot thecollar and the spring 8G.

The spring` 80 is angularly bent upwardly, the end portion 01 thereotfbeing horizontally disposed and provided with a contact projection 92adapted to coact with the upper tace o1 a contact member 93 arrangedwitiin the upper end ot the bore 94 o1 the shaft (S5 and insulatedtherelroin by an interposed sleeve 95. The contact member 93 iselectrically connected with one end et an insulated wire 0G extendingthrough the axial bore ot the stub shaft and leading to the lamp proper1111 mounted in the lamp head.

T he spring arm 80 o1 the switch is adapted to be operated, to open andclose the circuit, by an Lshapcd lever 97 pivotally supported from thepartition 78, the saine being mounted on a pivot 08 having its oppositeends :tixed ina pair ot upstanding lugs 99 at the front end o1' thepartition. The upper arni ot the lever 97 is sulistantially horizontallydisposed and has a tip ot insulating `material 100 coacting with thehorizontal portion et the spring 80, secured thereto in any suitable manner. The other arni oit the lfshaped lever 07, which is verticallydisposed, extends in liront ot the wall 1(57 and the lower end thereofis adapted to coact with a push rod 101 extending axially through thebore et the split shaft 621 and slidably movable therein. The rear endot the push rod 101 pro trudes beyond the gearl!) and provided with ahead 102. r1 helical spring` 103 surrounding the end ot the push rod andinterposed between the head 102 thereof and the outer end tace 01 thegear 59 serves to yieldingly retain the rear end et the red projected,as clearly shown in Figure 1. As will be evident, upon `)location ot therod 101, the L-shaped lever 97 will be oscillated thereby operating thearia 80 to make and break the circuit, the lever depressing the arm tocomplete the circuit when the push rod 101 is moved :torwardly.

The push rod 101 is adapted to be recipro catedby an oblong cani block101 rotzilably mounted on a pin 105 secured in a lug 100, said lug beingformed integral with and pro truding` inwardly trom a detachable plate107 forming the end wall ot the housing 125. A lever arm 10S formedintegral with the cani block l101 and extending through a vertical slot109 in the plate 107 serves as a linger piece tor operating the cani..To retain the cani block 10st in either et its extreme positions olmovement, the same is provided with llat end and side faces adapted tocoact with a bowed lea spring 110 iii-Led at its lower end to the plate107, by rivets or any other suitable torni oit securing means. lv'hcnthe tin ger jiece 108 is in the depressed. position shown in Figure 1,the circuit is open, the rod 101 being held in its retracted position bythe spring 103 and the horizontal arni ot the L-shaped lever J7 being inthe elevated pesiv tion shown7 thereby permitting the spring arm S0 toremain out ot contact with the block 03. To close the circuit, thelinger piece 1015 is moved upwardly turning the cani block through auare ot 900. 11s the cani block .is turned, the rod 101 will beprojected, swinging the lever 07, moving the tip 100 into contact withthe s iiniug arlu 00 and pressing the li ttor against the plug 023. 1twill be evident that the flat spring 110 engaging the tree end ot thefuni block retainsthe saine in position, thereby maintaining the circuitclosed. lllhen the finger piece is again swung downwardly to theposition shown in Figure 1, the push rod 101 will be tree to inoverear\.vardly und will be lforced again to the position shown in Figure1, permitting tree movement o1 thc I shaped lever 07, whereupon thespring arm 80, due to its resilience7 returns to original position7thereby brr-iaking the circuit.

As will be evident, the linger piece prow vides a very convenient meansfor opening and closing the circuit, the operator being able tomanipulate tle saine by one ol his lingers or thumb of the saine handeiigzugiiig the hand grip L15 without removing his hand from the latter.

The lainp head B comprises a shell 111 ot suitable construction, theshell carrying the usual lens 112 and reflector' mirror 113 to getherwith the electric lamp bulb proper indicated at 1111. The electric lampbulb is mounted for adjustment with respect to the reflector 113 so asto obtain proper ilocusing ot the light, this being accomplished by thefollowing means: The lamp bulb 111 is mounted in an externally threadedsocket member 115 provided with the usual bayonet slots 116 coactingwith the usual pins on the bulb for holding the same within the socket.The socket member 115 has an annular flange at the rear end thereofprovided with peripheral teeth, thereby providing an integral spur gearmember 117. The socket 115 is screwed into an internally threaded sleeve118 rigidly secured to the rei-lector 113 in any suitable manner. Itwill be noted that upon rotation of the sleeve in the proper direction,the saine will be screwed inwardly or outwardly with reference tothesleeve 115, thereby adjusting the lamp bulb relatively to the reflector.rlhe spur gear 117 meshes with an elongated spur gear 11.9 fixed to ashort shaft 120 journaled in a sleeve`121 rigidly secured within anopening in the rear wall oit' the shell 111. The shaft 120 is providedwith an integral, slotted screw head 122 for rotating the same. Uponrotation etl the shat't 120 by means o't a screw driver, the gear 11Twill be rotated through the gear 119, ettecting rotation ot' the socket115, screwing the same inwardly or outwardly of the sleeve 118, therebyeffecting adjustment of the lamp bulb.

A block of insulating material 123 is rivcted 'to lthe rear wall of thehead B, carrying a contact spring member 124 secured thereon by screwsor any other suitable means. rlhe tree end o1 the spring 124 isreversely bent as indicated at 125 and has its tree end bearing on. thecontact point oi' the lamp bulb 114. The opposite end of the spring 124is electrically connected to the wire 9G leading from the plug 93. Thebowed arm of the spring 124 which yieldingly bears on the end of thebulb maintains electric Contact therewith while the saine is adjustedinwardly and outwardly and also holds the pins on the bulb in yieldingengagement with the short ends the bayonet slots of the socket 115.

In the manufacture, shipping and assembling ot my improved device, Iprefer to adopt the iollowing procedure, the casing A., the arm 33, thehollow shai't 63, the sleeve 3G and all other parts to the left of thepost 20 as viewed in Figure 1 will be assembled as one unit and soshipped. In assembling the device, it is only necessary to bore a holethrough the post 20, whereupon the said unit may be assembled with thepost and the brackets 22 secured in place by the screws provided forthat purpose. Next, the bracket 37 with the sleeve 40 therein is slippedover the casing 36 and secured to the postby means of screws providedfor that purpose, the arms 39 being irst bent to iit the post; The nut41 is then screwed home, clamping the casing 3G securely to the bracket37. The handle supporting casting or housing 43 is assembled, shippedand applied as a unit, the same carrying the operating lever 108, thecam block 104, the spring arm 110, the hand grip 45, the gears 49', 54and 59 and the push rod 101 having the spring 103 thereon, so that, whenthe rod 101 is telescoped within the sha-'tt 63 and the housing' slippedover the extended end ot the arm 33, the gear 59 will make non-rotatableconnection with the square end portion of the hollow shaft G3.

AThe casting 43 is 'then tightly clamped to the operating arm 33 bytightening the screw 48. By adopting this procedure, it is evident thatthe device may be applied to acar without the aid of skilled labor, theonly tools needed and a housing supporting said head, said" lamp headextending to one side of said housing; mechanism for electing rotationof said head and housing about axes at an angle to each other, includinga single operating handle; an electric circuit; a switch within saidhousing in line with said head; and operating means for said switch,including a mov-` able linger piece mounted adjacent said handle.
